Erfindungagemäß ist also eine nicht-schmierende Kapselpumpe mit einem Gehäuse, einer Welle für die Flügel und einem Rotor vorgesehen. Der Eotor ist drehbar in zwei Lagern gelagert. Sines dieser beiden Lager sitzt auf einem Stützteil für das Rotorlager, das mit der Welle für die flügel verbunden ist, exzentrisch hinsichtlich der letzteren und in solcher Art, daß der Umfang der die Flügel tragenden Welle in den Umfang des Stützgliedes für das iiwxäjtgxx Rotorlager einbeschrieben ist, ehe dieses Stützglied an dem Gehäuse dadurch befestigt wird, daß es in dieses hineingeschoben wird.According to the invention, therefore, a non-lubricating capsule pump provided with a housing, a shaft for the blades and a rotor. The eotor is rotatably mounted in two bearings. Sines of these two bearings sits on a support part for the rotor bearing, which is connected to the shaft for the blades, eccentric with respect to the latter and in such a way that the circumference of the shaft carrying the blades is in the circumference of the support member for the iiwxäjtgxx rotor bearing is before this support member is attached to the housing in that it is pushed into this.

des Flügels 6 hat keine Berührung mit der Innenwand des Innenraums. Der Flügel 6 wird durch einen Rotor 3 in Drehung versetzt, dessen Welle 4 exzentrisch hinsichtlich der Flügelwelle 5 angeordnet ist. Die. Rotorwelle 4 verläuft von einem axialen Ende des Rotors 3 nach außen durch einen von zwei Abschlußdeckeln des Gehäuses 2. Eine Scheibe 7 ist an dem nach außen stehenden Teil der Rotorwelle 4 befestigt, um.den Rotor 3 von außen anzutreiben. Der eine Deckel wird nachfolgend "Treibseitendeckel" genannt. Das andere axiale Ende des Rotors 3 sitzt in einem Rotorlager 9, das in einem Rotorlagertragglied, d.h. auf einem Lagerzapfen 11 sitzt, der mit dem anderen der beiden Deckel des Gehäuses 2 ein Stück bildet, und der nachfolgend als Deckel von der vom Antrieb abgewandten Seite bezeichnet wird. Die Flügelwelle 5 ist an diesem Deckel 1 befestigt, indem sie in diesen hineingedrückt ist. Um einen Druck auf die Fläche des Innenringes 9' des Rotorlagers 9 zu vermeiden, ist es erforderlich, wenn die Flügelwelle 5 in den Lagerzapfen T1 für das Rotorlager hineingetrieben wird, eine bestimmte Dicke t für den Rotorlagerstützzapfen 1· zwischen der Innenfläche des Laufrings 91 und der Flügelwelle 5 vorzusehen, was zu einem großen Durchmesser dieses Lagerzapfens 1 * führt. Dementsprechend muß das Rotorlager 9 und der Rotor 3 ' entsprechend groß ausgeführt werden. Unter diesen Umständen ist es sehr schwierig, die radiale Größe der Kapselpumpe zu reduzieren, ohne die Pumpkapazität herabzusetzen. Ee wurde ferner vorgeschlagen, die die Flügel tragende Welle 5 dünner' of the wing 6 has no contact with the inner wall of the interior. The vane 6 is set in rotation by a rotor 3, the shaft 4 of which is arranged eccentrically with respect to the vane shaft 5. The. The rotor shaft 4 extends from one axial end of the rotor 3 to the outside through one of two end covers of the housing 2. A disk 7 is attached to the outwardly projecting part of the rotor shaft 4 in order to drive the rotor 3 from the outside. One cover is referred to below as the "drive side cover". The other axial end of the rotor 3 sits in a rotor bearing 9, which sits in a rotor bearing support member, ie on a bearing pin 1 1 , which forms one piece with the other of the two covers of the housing 2, and which subsequently acts as a cover from the one facing away from the drive Page is referred to. The vane shaft 5 is attached to this cover 1 by being pressed into it. In order to avoid pressure on the surface of the inner ring 9 'of the rotor bearing 9, it is necessary, when the vane shaft 5 is driven into the bearing journal T 1 for the rotor bearing, a certain thickness t for the rotor bearing support journal 1 between the inner surface of the raceway 9 1 and the vane shaft 5 to be provided, which leads to a large diameter of this journal 1 *. Accordingly, the rotor bearing 9 and the rotor 3 'must be made correspondingly large. Under these circumstances, it is very difficult to reduce the radial size of the capsule pump without reducing the pumping capacity. It was also proposed that the shaft 5 carrying the wings be thinner '

In den Figuren 2 und 3 ist eine bevorzugte Ausführungsform der Erfindung dargestellt, die nachfolgend besehrieben wird. Die Beschreibung dient jedoch nur zur Erläuterung der Erfindung, wobei diese nicht auf das besondere Verfahren und die dargestellte und beschriebene Konstruktion beschränkt ist.In Figures 2 and 3 is a preferred embodiment of the invention, which is described below. However, the description serves only to explain the invention, and this does not apply to the particular method and the shown and described construction is limited.
Erfindungsgemäß wird zuerst die Flügelwelle 5 an dem Lagerzapfen 11 für das Rotorlager befestigt,und dann werden dieser Lagerzapfen 1· zusammen mit der Flügelwelle 5 an dem Deckel 1 befestigt, d.h. dem Deckel an der nicht angetriebenen Seite, während bisher zuerst der Lagerzapfen 1' an dem Deckel 1 befestigt und erst danach die Flügelwelle 5 in den Lagerzapfen 1 * für das Rotorlager hineingepreßt wurde. In jedem Fall wirde das dünnere !Teil in das dickere Teil hineingedrückt, um das erstere mit dem letzteren zu verbinden. Durch die Arbeitsfolge gemäß der Erfindung ist es möglich, die Flügelwelle ^exaentrisoh hinsichtlich des Lagerzapfens 1 * für das Rotorlager und zwar so anzuordnen, daß der Umfang des ersteren vom Umfang des letzteren umschrieben wird. Hit anderen Worten, es ist möglich, die Dicke t, die bei den bekannten Vorrichtungen nötig war, wegfallen zu lassen, wodurch die radiale Größe der Kapselpumpe redussiert werden kann, ohnt dit Pumpenkapazität, die Festigkeit und die Dauerhaftigkeit der Welle und der Lager suAccording to the invention the wings shaft is first 5 attached to the bearing pin 1 1 of the rotor bearing, and then this bearing pin 1 · fastened together with the wing shaft 5 on the cover 1, the cover that is on the non-driven side, whereas in the past, first the bearing pin 1 ' attached to the cover 1 and only then the vane shaft 5 was pressed into the bearing pin 1 * for the rotor bearing. In either case, the thinner part is pushed into the thicker part to connect the former to the latter. By the work sequence according to the invention it is possible to arrange the vane shaft ^ exaentrisoh with respect to the bearing journal 1 * for the rotor bearing in such a way that the circumference of the former is circumscribed by the circumference of the latter. In other words, it is possible to omit the thickness t, which was necessary in the known devices, whereby the radial size of the capsule pump can be reduced, without the pump capacity, the strength and durability of the shaft and the bearings see below

"beeinträchtigen. Da der Durchmesser des Rotors 3 reduziert wird, ohne den Innendurchmesser des Gehäuses 1 zu ändern, wird die effektive Fläche des Flügels 6 vergrößert, so daß die Pumpenkapazität der Pumpe gesteigert wird.Since the diameter of the rotor 3 is reduced without changing the inside diameter of the housing 1, the effective area of the vane 6 is increased so that the pumping capacity of the pump is increased.
Ferner muß, wenn ein Teil in ein anderes hineingedrückt werden soll, in dem letzteren zuerst ein geeignetes Loch hergestellt werden.Furthermore, if one part is to be pressed into another, a suitable hole must first be made in the latter getting produced.
